Application filed July 18,

This invention relates to concrete build ing structures, and particularly the centering and supports for forming floors and ceilings lIllBlGO'l.

l 'nll the principal feature of the invention ire-- sides in the means "for supporting the filling 'l'orins and adj listing the same to various heights with respect thereto for obtaining varying depths oi floor heanis. 'lfhis is accomplished by providing a supporting inen'iher having a plurality of recesses termed therein to selective engagement with suitahle flanges extending laterally of the side walls of the centering; tor-ins.

"he tell. nature ot the invention wi l he understood i'roin the accompanying drawings and the following description and claims ll." 1 is a perspective view showing the as semhly ot the various units for :tori'ning floor and ceiling; structures of concrete or the like. i 2 section taken on the line 2-2 of Fig. 1. 3 is an enlarged perspective view of the adjustable tiller or soffit support. l ipj. l is a zinodilied term of soilit chair, showing a perspective view thereof.

1n the drawings there is shown a structural support comprising the ledger beams and 11 termed of structural channels or tinihcrs, which are supported. at intervals by the adjustable shore 12 which comprises telescopic tubular posts adjustable with res, set to each other by means of a pin 13 extending through suitable holes in the lower nieinljier upon wh ieh the lower end of the upper inernher rests in adjusted position with respect to height. lhe lower member is supported by the nut 14-. adapted to screw upon the srrcw-threaded hose 1?). Y

'lhe centeriiuz; 'lorins comprise a plurality or": sheet metal incnihers 16 which are oilinverted ,l-suipe in cross section when placed in position, adapted to rot adjaccnt their ends upon he lodgers it and 11. Plaid centering; forms rosy he made ol. any desired shape in cross section suitahle for theiorniation ot the conrrete thior and ceiling;- oi'. the building, and the sheet metal of which they are formed may he oi any desired thickness or strength to ohtain the proper length and breadth. They may also he continued in sections wherein a ilurality oi sections are positioned in align ment with each other, the ends of adj accnt sect'ions over-lapping each other in the usual manner as indicated at 17.

Each oi? the centering forms are provided with laterally extending flanges 18 extending 1928. flerial lilo. 293,@%.

the lull. lei k l. thereof, said flanges being formed by turning the longitudinal edges oi the lower portions thereof upwardly at an acute angle so as to extend at anangle oil. approximately forty-five degrees to that of the side w: lie of the torus-s. feiup ported at intervals hetwcen the led rgers 1t) and ll by the adja cent llunges ill, and hetwcen the corresponding centering terms there are novidcd a plurality ot soliit chairs comprising the top plate ll) sup ported adjacent to but spaced from the ends thereof by the ill-shaped chair supports 20. loaid supports are formed of a channel oar hent ll-shapcd in general. contour with the flanged legs thereof extending downwardly. 1n the legs, there are cut a plurality of recesses spaced apart in vertical relation, and extending inwardly and upwardly at an acute angle adapted to receive therein the up- Wardly hent flanges 18 of the centering forms, as host illustrated in Fig. 3.

When the sol'tit chairs are mounted in. position, they are supported by the selective engagement of the flanges with the recesses,

give thetop plate 19 thereof the desired to depth with respect to the top of the centering; lorins. This gives the proper depth oi the ceiling heanis to he termed. Spanning the space intermediate the adjacent ends at the soilit chairs tnere are provided sollit plates or hoards ll y means of this arrangcl'nent, the shoring for the lodgers niayhe quickly set up to the proper hoi dit, the shoring put in placean d the 'iOl'lllFl i'iuninted thereon. The st "1 chairs are interposed hetwecn the forms as they are put in lace so that the top plates thereol are poi-tic. l at th proper depth. 'l his depth maintained unirorn'l hy selectively interlocking the flanges off the ccnterinp; forms with the similarly positioned. recesses 21. The top plates and so'liit plates; or hoards are then laid on top ol' the sol'litchairs so as to he supported therehy and the concrete is then ready to he poured. litter the concrete has been sinliciently the shoring may he removed and the lodgers taken down, whereby the centering forms with the sollit chai s may he removed and pern'ianent shorin mounted in place to engage the :so'l'lit plates or hoards lor continuing to support the concrete until it is finally set with full strength.

As shown in the modified form, Fig. 1, the sofiit chair comprises an elongated top plate 119 having its ends hcnt downwardly U!- shaped to form the legs 120, and suitably are provided with the recesses 121 for the *same purpose as above described With respect to the recesses :21. The soffitchair ribbed for? strengthening purposes. The legs o in Fi o. no invention claimed is:

- 1. In a concrete structure, a plurality oi centering forms 'havin laterallyextending flanges thereon, and means interlocking with saidtlanges for supporting the concrete interto said form's. t
